Yeah, the skirt from the mentioned picture needs to be added for the Romulan faction. It was obviously intended to be a part of the outfit for females as the artwork for it has been done. I have no idea why it's not availible, I hope it's somekind of bug/glitch that can easily be fixed.

And please Cryptic, don't dare pulling the warrior's skirt stunt on this one, we have many things to waste lobi on as it is. This needs to be a part of the Fed.-alligned outfit and any other skirts you add in the future should go to C-Store.
